Animal Welfare in Intensive Egg Production

The global egg industry confines billions of hens in conditions that cause significant, chronic suffering.

Key Facts

Approximately 8 billion hens globally produce eggs in intensive cage systems
Colony cage systems, while larger than battery cages, still prevent most natural behaviors
Beak trimming — removing part of the beak — is routine to prevent cannibalism in overcrowded conditions
Enriched colony cages are now EU standard but remain inadequate for full behavioral expression

Welfare Considerations

Intensive egg production confines hens in conditions that prevent most natural behaviors — dust bathing, wing flapping, foraging, and establishing stable social hierarchies. Beak trimming, while reducing cannibalism, is itself a welfare concern — the beak contains dense nerve endings and trimming causes acute pain and may cause chronic discomfort. The transition from battery to enriched colony cages in the EU improved some outcomes while leaving others unaddressed. Full behavioral freedom requires aviary systems with adequate space and enrichment.

What You Can Do

Choose eggs from verified aviary or free-range systems with outdoor access
Reduce egg consumption to lower demand from intensive production
Advocate for beak trimming bans contingent on adequate stocking density reductions
Support welfare certification requiring outcome-based hen welfare assessment
